In this sequel to Post-Human, humanity will be forced to face a future more advanced than it could have imagined if it wants to survive. Nineteen months have passed since the AI turned against humanity and was subsequently destroyed. In the meantime, James Keats has turned over the AI's powers to a non-intelligent, easily controlled operating system. He and Thel have left the planet and spent six months vacationing on Venus, which has been newly terraformed without the consent or knowledge of the Governing Council. The AI has been deleted, but the message it sent out into the abyss of space in search of a companion has been answered. An alien force dwarfing the Earth is on its way to find out why the AI has stopped communicating. Keats and company can only assume its intentions will be hostile when it finds out the truth. Only one thing is for sure: nothing will ever be the same again. Welcome to the Trans-Human era. Welcome to the singularity.

Imagine an alternate reality that appears, on the surface, just like our own. However, in this reality, the white light famously reported at the end of our lives is not an escape or deliverance ——it is a trap. A creature calling itself God in a parallel dimension consumes the souls of humans, devouring their energy to sustain itself. This is the reality that Cipher, Han, Natalie and Father Hurley inhabit in The God Killers. Each has had near death experiences (NDE's) and each was resuscitated before their souls were consumed, coming back to Earth horrified by the truth: there is no exit. 

Now they must attempt the only course of action available to them: they must kill God. With the help of satanic messages decoded from the nonsensical ramblings of the possessed, the group must evade ghosts and demons on their mission to not only save their lives, but, more importantly, their afterlives as well.
